I'm an omnivore. Although there might be individual exceptions, there's no evidence that human beings can live long-term without animal protein. I'm thrilled about the organic/free-range movement. We can do much more to give animals a higher quality of life and grow grains, vegetables, and fruit without using fossil-fuel based fertilizers.
that is a fallacy, it is completely possible to get full chain amino proteins from sources other than animals. I don't disrespect anyone's choices, but please don't spread misinformation about vegetarian/vegan diets.
